MainLoop

MainLoop, as the name might suggest, is a main loop built with C++. It includes calculating the delta time between updates for the programmer to use for calculations, timings, physics, or whatever you need delta time for. MainLoop can be dropped into any project as a single header.

Examples

A Sample Text RPG Simulation using this loop

#include "MainLoop.h"

    std::cout << "Enter your character's name: ";
